In a machine for packaging rolls of household paper products, packs are restrained between groups of vertical teeth associated with a conveyor passing through a wrapping station, a folding station and a heat seal station; equipping the wrapping station with additional vertical teeth fixed to a support afforded by the machine which are positioned alongside and offset from the group of conveyor teeth remote from the folding station, at a distance from the remaining group of conveyor teeth less than the distance which separates the two groups of conveyor teeth, a tighter restraint can be applied as the rolls are enveloped initially in the relative sheet of wrapping film, whereupon the movement of the conveyor teeth beyond the station will allow the sheet to slacken, and the rolls to regain their normal shape.
